"The Matrix""star Keanu Reeves is allegedly being stalked by an obsessed fan of the movie who thinks the actor's character, Neo, is real.

TMZ obtained legal documents indicating the Los Angels police department is searching for a man who showed up at Keanu's home in October 2015 and places a FedEx envelope in his mailbox, along with a cell phone and the following note: "I will call the cell provided tomorrow. We need to meet as I have already started building the new world. #masterbuilder."

Fans of the first installment of the "Matrix" franchise will know that the cell phone is a nod to the film's plot.

Keanu, understandably, is worried about his safety because this man knows where he lives. The actor fears the obsessed fan suffers from a mental disorder. This isn't Keanu's first or even second time dealing with a scary stalker.

As we previously reported, the actor faced two home intruders days apart form each other in September 2014. In the first incident, Reeves was home and confronted the intruder in his library before calmly calling 911. The woman was also taken to a medical facility for psychiatric evaluation.

Days later, a second woman broke into his home and wasn't wearing any clothes. Keanu wasn't home at the time of the second incident, but his staff called the police. The woman was reportedly using hthe actor's shower and swimming in his pool. After the suspect was apprehended, she was taken in for mental evaluation.
